Adderall 20mg is a commonly prescribed dose of a medication used to manage symptoms of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is a combination of two stimulants, amphetamine and dextroamphetamine, which work together to increase focus, concentration, and alertness. At this dose, Adderall can help individuals with ADHD to better control their symptoms, such as restlessness, impulsivity, and inattention. For those with narcolepsy, it can reduce daytime sleepiness and help maintain wakefulness throughout the day.
